Patent ES-447180-A1 (ES)
Title: Method and apparatus for the automatic communication of two telephone subscribers
IPC: H04M3/42
Filed: 1976-04-09
Abstract: Automatic communication establishment between two telephone subscribers of different exchanges. The identities of the caller and the called are transferred to the called exchange in the event that the called line is busy, permitting disconnection of the two exchanges. The called's line is thereafter monitored until becoming free upon which the caller's identity is utilized by the called's exchange for calling back the caller. If the caller's line is now busy, the transfer of the called and the caller's identities take place again, this time back to the caller's exchange. The caller's line is similarly monitored until free, after which the method is repeated until communication is established.

Title: Polymerisation of vinyl chloride
IPC: C08F14/00
Filed: 1976-07-13
Abstract: According to the invention, vinyl chloride monomer or a monomer mixture essentially comprising vinyl chloride is polymerised in a polymerisation reaction whose internal walls and stirrer and other surfaces which come into contact with the monomer or the monomers have been coated with a mixture of at least one electron-donor compound and at least one electron-acceptor compound. This method greatly reduces the deposition of polymer crusts on these surfaces, and a high-quality polymer can be produced.

IPC: C02F3/20
Filed: 1976-12-31
Abstract: Aerobes are employed to stabilise waste water and/or organic sludge by treating with oxygen or a gas which is rich in oxygen. The fluid contents of a treatment vessel is induced to circulate about a horizontal axis. The contents rotate like a cylinder and there is negligible movement in a central zone arround the axis of rotation. Oxygen or a suitable gas rich in oxygen is injected into this central zone of the fluid. as it rotates. Used for stabilisation of waste water and/or sewage sludge by aerobic treatment, partic. material contg. highly concn. organic matter such as cattle shed drainings sludge from foul sewers and excess sludge from waste water treatment. The organic activity is reduced to a level at which the fluid can be easily clarified by conventional treatment. The fluid is cleaned and stench reduced to make it suitable in preparing agricultural fertilisers. No moving parts in treatment vessel. Remarkably high utilisation of injected oxygen, i.e. 90% to 100% is distilled.

The refacing tool restores the seating surfaces of the torch nozzle and represents a considerable savings to the welding industry which heretofore was not realized.
Patent ES-468509-A1 (ES)
Title: Internally coated reaction vessel for use in olefinic polymerization
IPC: C08F2/00
Filed: 1978-04-03
Abstract: This invention relates to a polymerization reaction vessel having an approximate monolayer coating on the inner surfaces thereof which is obtained by applying thereto an aqueous coating solution containing a tannin, such as, for example, tannic acid.

Title: Electric vehicle motor regulation unit - monitors amplitude of armature current determined by divider gate set by vehicle switch
IPC: H02P7/298
Filed: 1979-12-14
Abstract: The regulation unit is for a current-controlled vehicle motor supplied by a control current, w.r.t. the motor stray field, the regulated-amplitude of the armature current is fixed via a divider-gate, whose divider stage is set via the vehicle switch. The armature of the vehicle motor is fed from an armature-current regulator via a smoothing choke, while the field winding is connected to a current regulator. Control of the armature-current-regulator is determined by the control angle of the valve and a control voltage, for which the control-amplitude is set via a potential-dividing transformer from the armature-terminal voltage. The lead-amplitude for the armature voltage is provided via a pre-set transmitter. The control deviation in the amplitudes guides the voltage regulator, whose output amplitude corresps. to the current regulation and sets the lead amplitude for the armature current.

Patent ES-8100122-A1 (ES)
Title: Simplified foundry core making machine and method
IPC: B22C13/08
Filed: 1980-03-12
Abstract: A foundry core making machine is disclosed which produces large or fragile cores. The core is initially made in two parts, which are later adhered together by movement between first and second stations. The separate core halves are made in third and fourth stations and then relatively moved to be in the first and second stations, vertically one above the other, and with flat surfaces facing each other. The core box booking means is utilized to move the lower core half upwardly against the upper core half to have the two adhere together. This same booking means was previously used to press vent grooves in one core half so that when the two core halves were assembled, a generally centrally extending core venting aperture was established. The core box ejection means then ejects the completed core from one core box in a carefully controlled movement. The foregoing abstract is merely a resume of one general application, is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter.
